html <div> doesn't seem to get recognised

本文关键字：seem to get recognised doesn lt div gt html 更新时间：2023-09-26

似乎没有得到认可。

我有2个部门。一个用于页眉（ head-top ），另一个用于页面中其余空间（centre），如下所示。我已经将单击事件附加到标题中的元素。但这些元素似乎不起作用。我无法单击切换菜单。什么也没发生。我在菜单栏中有 2 个按钮和一个切换菜单。

.HTML：

<div class="head-top">
            <div class="menu-links">
                <ul class="toggle-menu">
                    <li class="toggle">
                        <span class="toggle-menu-bar"></span>
                        <span class="toggle-menu-bar"></span>
                        <span class="toggle-menu-bar"></span>
                    </li>
                    <li class="content0" style="display: none">
                        <ul>
                            <li><a href="#" id="home">Home</a></li>
                            <li><a href="#" id="explore">Explore</a></li>
                            <li><a href="#" id="searcha">Search</a></li>
                            <li><a href="#" id="recent">Recent</a></li>
                        </ul>
                    </li>
                </ul>
            </div>
            <div id="b1">Sign Up</div>
            <div id="b2">Upload</div>
        </div>
            <div class="center">
                <div class="middle">
                    <h1>The Starry Night</h1>
                    <span><br>Vincent van Gogh</span>
                </div>
            </div>

.CSS：

.head-top {
  width: 90%;
  height: 15%;
  position: relative;
 }
.center {
  background: rgba(0, 0, 0);
  text-align: center;
  position: absolute;
  color: #000000;
  bottom: 0;
  right: 0;
  left: 0;
  top: 0;
  cursor: pointer;
}
.middle {
  position: absolute;
  margin-top: -6em;
  right: 0;
  left: 0;
  top: 50%;
}

点击事件：

 $('li.content0').hide();
  $('ul.toggle-menu').delegate('li.toggle', 'click', function () {
        $(this).next().toggle('fast').siblings('.content0').hide('fast');
    });

您的.center元素覆盖了整个head-top元素。让我们找到另一种制作CSS的方法，您尝试存档，以进行修复，删除并留下以下内容：

.center {
  background: rgba(0, 0, 0);
  text-align: center;
  color: #000000;
  cursor: pointer;
}
